Resumen
La rinitis alérgica, que afecta al 20% de los estadounidenses, implica la exposición a alérgenos que desencadenan respuestas inmunes. El manejo incluye la evitación, medicamentos como antihistamínicos y esteroides intranasales y inmunoterapia.
Área de la Ciencia:
- Inmunología Inmunología.
- Investigación de Alergias Investigación de Alergias
Sus antecedentes:
- La rinitis alérgica afecta aproximadamente al 20% de la población de los Estados Unidos.
- El diagnóstico se basa en los patrones de síntomas, exámenes físicos y pruebas de anticuerpos IgE.
- Los desencadenantes comunes incluyen polen, hongos, alérgenos animales y ácaros del polvo.
Objetivo del estudio:
- Para esbozar la fisiopatología de la rinitis alérgica.
- Para describir los enfoques de diagnóstico.
- Revisar las estrategias de manejo de la rinitis alérgica.
Principales métodos:
- Revisión de los criterios de diagnóstico para la rinitis alérgica.
- Análisis de los mecanismos inmunológicos subyacentes a la inflamación alérgica.
- Evaluación de las actuales intervenciones terapéuticas.
Principales resultados:
- La exposición al alérgeno inicia la liberación rápida del mediador de mastocitos, seguida de la participación de los eosinófilos y los linfocitos.
- Las citoquinas T(H) 2, incluidas las interleucinas-4 y -5, son clave para orquestar la inflamación alérgica.
- Los cambios en los tejidos causados por la inflamación exacerban los síntomas y las reacciones posteriores.
Conclusiones:
- El manejo efectivo requiere evitar los alérgenos.
- Los síntomas de la rinitis alérgica intermitente se tratan con antihistamínicos y descongestionantes.
- Los síntomas persistentes pueden requerir esteroides intranasales, con inmunoterapia como una opción para los casos refractarios.

Asthma I: Introduction
Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...
Drugs Used in Upper Respiratory Disorders: Overview
Upper respiratory tract disorders, including viral infections and allergic rhinitis, cause significant discomfort and disrupt daily life. Managing these conditions involves a variety of drugs, such as antihistamines, intranasal steroids, decongestants, antitussives, expectorants, and mucolytics. Specific examples of drugs in each category are provided.
Antihistamines (e.g., Benadryl) block histamines from binding. Histamines are chemicals released during an allergic reaction in the body. As a...

Asthma-I: Introduction
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Overview
Upper Respiratory Drugs: Decongestants
Decongestants are a class of medications used primarily to alleviate nasal congestion, a common symptom resulting from allergies, colds, sinusitis, and other upper respiratory tract infections. These drugs work by activating α-adrenergic receptors, constricting small blood vessels in the nasal membranes. This action results in the opening of clogged nasal passages, thereby facilitating sinus drainage and relieving congestion.
Most decongestants are readily available over-the-counter in various...

Allergic Reactions: Anaphylaxis
Anaphylaxis is a severe, life-threatening hypersensitivity reaction mediated by Immunoglobulin E (IgE) antibodies. When IgE binds to allergens, it triggers the release of mediators– histamine, leukotrienes, and prostaglandins from mast cells and basophils. These mediators cause vasodilation, edema, and inflammation, leading to various symptoms.The primary allergens causing anaphylaxis include food items (e.g., peanuts, shellfish), drugs (e.g., penicillin, asparaginase, corticotropin, heparin),...
